A bottle of beer is cooled using the new magnetic refrigeration system developed by GE

The fridge is the most common of common household appliances. Despite improvements in efficiency over the years, they remain one of the biggest users of electricity in the home, relying on chemical refrigerant and a compressor to transfer heat from the inside to the outside of the fridge. GE researchers have now developed a new type of refrigeration technology using magnets that is more environmentally friendly and is predicted to be 20 to 30 percent more efficient that current technology ... and it could be in household fridges by the end of the decade.  Read More

The Solar Cooler from Solar Cool Technologies at CES 2014

In the past, we've seen solar ovens that can whip up a hot meal using only the sun's rays, but Solar Cool Technologies has a new product that harvests that same energy to accomplish just the opposite. We quite literally crossed paths with the Solar Cooler and its designers at a Las Vegas casino during CES where they were showing off the new Solar Cooler. The Solar Cooler, as its name implies, is a portable container for food and drinks that keeps its contents cold using a compact refrigeration system connected to solar panels.  Read More

The US Department of Energy will be using fuel cells to power the refrigeration units of f...

The refrigeration units used in cold transport trailers are typically powered by small diesel engines, which use up non-renewable fuel and release greenhouse gases, just like their big brothers. The US Department of Energy, however, is looking into an alternative. As part of a two-year pilot project, it’s equipping four such trailers with clean-running hydrogen fuel cells.  Read More

The new Euroengel compressor refrigerated container allows standard vehicles to carry cold...

Eberspächer is best known for its OEM work with vehicle manufacturers in the field of exhausts and heaters, but the company's new Euroengel compressor refrigerated range directly targets end users. The portable lightweight refrigerated boxes can reportedly be temporarily fitted to almost any commercial vehicle, and are transferable between vehicles. A 12 or 24-volt socket (cigarette lighter) is sufficient for all boxes and when stationary, they can be plugged into any mains electricity supply system in the world, from 110 to 240 volts. The cost-effectiveness in comparison to a refrigerated vehicle conversion is impressive, as purchased or leased vehicles can be retrofitted to become refrigerated vehicles, then sold or returned in original condition.  Read More

Lidija Pritrznik, Creative Director and member of Gorenje's design team designed the SmarS...

With its retro good looks and smooth lines, the SmarSofa from Gorenje wouldn’t look out of place on an Austin Powers movie set. On display at IFA 2010, the SmarSofa is not just a convertible lounge. It includes a fully integrated fridge which contains remote-controlled, rotating cooling platters. At the touch of a button the platters containing ready-to-eat dishes can be lifted and lowered to the desired height. How’s that for groovy?  Read More

UM researchers will test a prototype cooling system using a thermoelastic 'smart' metal th...

Many readers would be familiar with the electrical blackouts that occur in the summer months resulting from the extra load placed on electricity supplies by air conditioners. A new “smart” metal being developed by researchers at the University of Maryland (UM) could help cool homes and refrigerate food 175 percent more efficiently than current technology, not only giving strained electricity networks a bit of relief, but also drastically cutting summer electricity bills and greenhouse gas emissions.  Read More

Jeff Kortright and Sujoy Roy (right) from Berkeley Lab - that thing in front of them is NO...

In the future, your refrigerator might keep your food cold by using a magnet. Not only would it use less power and run quieter than your current fridge, but it also wouldn’t contain any hydrofluorocarbons, gases which can add tremendously to the greenhouse effect if not properly disposed of. It all comes down to something called the magnetocaloric effect, wherein a changing magnetic field within a material causes it to get colder. It definitely holds promise, although scientists first have to figure out just how the thing works.  Read More

At this winery, the solar collector at the front drives the absorption refrigeration machi...

The sun is already being used to power air-conditioning systems so it seems a natural progression to apply it to refrigerate perishable foodstuffs - a huge consumer of fossil fuel-based energy. Scientists from the Fraunhofer Institute for Solar Energy Systems ISE in Freiburg, Germany, are taking this task to heart with two solar refrigeration trials in the Mediterranean region – one at a Tunisian winery and the other at a dairy in Morocco.  Read More

Is this the world’s cheapest refrigerator? Launched by Indian conglomerate Godrej and Boyce, ChotuKool's $69 price tag is not the only reason it can be called super economical. The portable, top-opening unit weighs only 7.8kg, uses high-end insulation to stay cool for hours without power and consumes half the energy used by regular refrigerators. This is a product that has crossed several technological barriers and is designed to cross several social barriers as well.  Read More

IIS solar refrigeration solution

A fridge that positively thrives in direct sunlight might seem a bit of a strange idea, but if you find yourself in a baking hot country where keeping your medical supplies cool and fresh could mean the difference between life and death, or you just want to sell some chilled refreshments to passers-by, then you need a portable, stand-alone chill solution. Industrial Insulation Systems (IIS) has developed a solar powered fridge/freezer which can be tailored to meet the needs of these off-the-grid scenarios.  Read More
